A mutual fund generally pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when mutual fund shares are held in a taxable account. The Portfolio does not pay transaction costs when buying and selling shares of other mutual funds (the "Underlying Funds"); however, the Underlying Funds pay transaction costs when buying and selling securities for their portfolios. The transaction costs incurred by the Underlying Funds, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Portfolio's performance. Because the Portfolio is new, information about portfolio turnover rate is not yet available.

This Example is meant to help you compare the cost of investing in the Selectively Hedged Global Equity Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio's operating expenses remain the same. The costs for the Portfolio reflect the net expenses of the Portfolio that result from the contractual expense waiver in the first year only. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

Dimensional Fund Advisors LP (the "Advisor") believes that equity investing should involve a long-term view and a systematic focus on sources of expected returns, not on stock picking or market timing. In constructing an investment portfolio, the Advisor identifies a broadly diversified universe of eligible securities with precisely-defined risk and return characteristics. It then places priority on efficiently managing portfolio turnover and keeping trading costs low. The Advisor does not intend to purchase or sell securities for the investment portfolio based on prospects for the economy, the securities markets or the individual issuers whose shares are eligible for purchase.

The Selectively Hedged Global Equity Portfolio is a "fund of funds," which means that the Portfolio generally allocates its assets among other mutual funds managed by the Advisor although it also has the ability to invest directly in securities and derivatives. The Portfolio seeks to achieve exposure to a broad portfolio of securities of both U.S. companies and non-U.S. companies associated with countries with developed and emerging markets, including frontier markets (emerging markets in an earlier stage of development), by primarily purchasing shares of U.S. Core Equity 2 Portfolio, International Core Equity Portfolio and Emerging Markets Core Equity Portfolio (the "Underlying Funds"). From time to time, the Advisor also may add or remove Underlying Funds in the Portfolio without notice to shareholders. The Advisor may consider the relative market capitalization weighting of developed and emerging markets within the universe of eligible securities along with other factors when allocating Portfolio investments among the Underlying Funds or securities. The Portfolio may have exposure to companies in all the market capitalization ranges.

As a non-fundamental policy, under normal circumstances, at least 80% of the Selectively Hedged Global Equity Portfolio's net assets will be invested directly, or indirectly through its investment in the Underlying Funds, in equity securities or investments that provide exposure to equity securities. In addition to, or in place of, investments in the Underlying Funds, the Portfolio is permitted to invest directly in the same types of equity securities of U.S. and non-U.S. companies that are eligible investments for the Underlying Funds.

The Selectively Hedged Global Equity Portfolio invests directly or indirectly though its investment in the Underlying Funds in securities that may be denominated in foreign currencies. The Selectively Hedged Global Equity Portfolio may hedge some or all of the currency exposure of the foreign securities by entering into foreign forward currency contracts, futures or other derivatives. The decision to hedge the Selectively Hedged Global Equity Portfolio's currency exposure with respect to a foreign market will be based on, among other things, a comparison of the respective foreign and U.S. short-term interest rates and the Portfolio's existing exposure to a given foreign currency. The Selectively Hedged Global Equity Portfolio and each Underlying Fund also may use derivatives, such as futures contracts and options on futures contracts for equity securities and indicies, to gain market exposure on its uninvested cash pending investment in securities or to maintain liquidity to pay redemptions. In order to meet segregation requirements with respect to such derivative transactions, the Selectively Hedged Global Equity Portfolio may hold short-term fixed income obligations.

The Selectively Hedged Global Equity Portfolio and each Underlying Fund also may invest in exchange-traded funds (ETFs) and similarly structured pooled investments for the purposes of gaining exposure to the equity markets, while maintaining liquidity. In addition to money market instruments and other short-term investments, the Selectively Hedged Global Equity Portfolio and each Underlying Fund may invest in affiliated and unaffiliated registered and unregistered money market funds. The Portfolio and Underlying Funds may invest in such money market funds and other short-term investments to manage cash pending investment in other securities or to maintain liquidity for the payment of redemptions or other purposes. Investments in money market funds may involve a duplication of certain fees and expenses. The Selectively Hedged Global Equity Portfolio and Underlying Funds may lend their portfolio securities to generate additional income.

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Fund of Funds Risk: The investment performance of the Selectively Hedged Global Equity Portfolio is affected by the investment performance of the Underlying Funds in which the Portfolio invests. The ability of the Selectively Hedged Global Equity Portfolio to achieve its investment objective depends on the ability of the Underlying Funds to meet their investment objectives and on the Advisor's decisions regarding the allocation of the Portfolio's assets among the Underlying Funds. The Selectively Hedged Global Equity Portfolio may allocate assets to an Underlying Fund or asset class that underperforms other funds or asset classes. There can be no assurance that the investment objective of the Portfolio or any Underlying Fund will be achieved. Through its investments in the Underlying Funds, the Portfolio is subject to the risks of the Underlying Funds' investments. The risks of the Underlying Funds' investments are described below.

Foreign Securities and Currencies Risk: Foreign securities prices may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or (b) less regulated or liquid securities markets. Investors holding these securities may also be exposed to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S. dollar or that a foreign government will convert, or be forced to convert, its currency to another currency, changing its value against the U.S. dollar). The Underlying Funds do not hedge foreign currency risk but the Selectively Hedged Global Equity Portfolio may directly hedge the foreign currency risk it is exposed to through its investment in the Underlying Funds or its direct investment in foreign securities. The Portfolio also may leave some or all of its foreign currency exposure unhedged.

Small Company Risk: Securities of small companies are often less liquid than those of large companies and this could make it difficult to sell a small company security at a desired time or price. As a result, small company stocks may fluctuate relatively more in price. In general, smaller capitalization companies are also more vulnerable than larger companies to adverse business or economic developments and they may have more limited resources.

Value Investment Risk: Value stocks may perform differently from the market as a whole and following a value-oriented investment strategy may cause the Selectively Hedged Global Equity Portfolio and the Underlying Funds to at times underperform equity funds that use other investment strategies.

Market Risk: Even a long-term investment approach cannot guarantee a profit. Economic, political, and issuer-specific events will cause the value of securities, and the Underlying Funds that own them, and, in turn, the Portfolio itself, to rise or fall. Because the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money.

Emerging Markets Risk: Numerous emerging market countries have a history of, and continue to experience serious, and potentially continuing, economic and political problems. Stock markets in many emerging market countries are relatively small, expensive to trade in and generally have higher risks than those in developed markets. Foreigners are often limited in their ability to invest in, and withdraw assets from, these markets. Additional restrictions may be imposed under other conditions. Frontier market countries generally have smaller economies or less developed capital markets and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries.

Derivatives Risk: Derivatives are instruments, such as futures and foreign exchange forward contracts, whose value is derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes may be considered more speculative than other types of investments. Derivatives can be used for hedging (attempting to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. The use of derivatives for non-hedging purposes may be considered more speculative than other types of investments. When the Portfolio or Underlying Funds use derivatives, the Portfolio will be exposed to the risks of those derivatives. Derivative instruments are subject to a number of risks including liquidity, interest rate, market, credit and management risks, and the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and the Portfolio or an Underlying Fund could lose more than the principal amount invested.

Securities Lending Risk: Securities lending involves the risk that the borrower may fail to return the securities in a timely manner or at all. As a result, an Underlying Fund may lose money and there may be a delay in recovering the loaned securities. An Underlying Fund could also lose money if it does not recover the securities and/or the value of the collateral falls, including the value of investments made with cash collateral. Securities lending also may have certain adverse tax consequences. To the extent that the Portfolio holds securities directly and lends those securities, it will be also subject to the foregoing risks with respect to its loaned securities.
